SPECIFICATION forming part of Letters Patent No. 591,305, dated October5, 1897.

Applicationfiied June 19,1897. serial No. 641,502. (Numan.)

Be it known that I, FRANZ S. THOMAS, of Salem, in the county ofWashington and State of Indiana, have invented certain new and usefulImprovements in Sawmill vAttachments; and I do hereby declare thefollowing to be a full, clear', and exact description ofthe invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

This invention relates to sawmillattachments, 'and the object is toVprovide a turnblock of simple and improved form for assisting in turningthe log upon the carriage to proper position for sawing. v

The `invention consists in the novel features of construction, and inthe combination and arrangement of parts hereinafter fully described andclaimed, and illustrated by the accompanying drawings, in which- Figurel'is an elevation, partly in section, of my improvement, the same beingin inoperative position. Fig. 2 is a similar view of the same inoperative position. Fig. 3 is a plan view.

Skid A, over which logs are rolled to carriage B, is formed withlongitudinal depression C, open a portion of its length at D and at therear end of opening Cvforming abutment E. Inclined track F is arrangedin the forward portion of opening C with its upper end extending to thetop surface of the skid, and adapted to slide on the track is themetallic-boundblock G, having its top and front edge curved, as shown atG. Link H is arrangedv to move'freely in opening'O and is hinged at itsforward end *toV block G, while at its rear end it is secured torock-arm I by top hinge J, 'said rock-'arm being secured to shaft K,journaled transversely in the skid.V

Whennot in use, the block is in lowered position on the track, as seenin Fig. l; with its top surface flush with the top plane of the skidand'its rear edge engaging abutment E. Vhen link H and Yarm I arestraightened out with their adjacent ends squarely engaging, (see Fig.2,) the turn-block is projected and rigidly held. The top edge of arm His reduced backward to form shoulder L, and when the arms are alined, asjust described, this ing moved to the carriage.

shoulder is raised to engagement with abut- Y ment E, so that adoubly-secure holding means for the block is provided.

For operating shaft K the same is provided with cogged segment M, whichmeshes with a similar segment on shaft N, and on this last-mentionedshaft is an arm O, connected by link P with operating-lever Q. In millsWhere the sawyer stands on the carriage side of the saw the arm O, linkP, and lever Q are preferably arranged in lowered position beneath theiioor, as shown in dotted lines.

The operation of the device will be readily understood by those skilledin the art. The block when not in use is in lowered position andentirely ont of the way of the logs in beside of the log and it isdesired to turn same to sawanother side the block is raised and rigidlyheld, as described, and the log being turned thereagainst, as shown inFig. 2, is

- turned automatically to proper position, the

curved inclination of the head causing the log toY moveV back on thecarriage in proper position for sawing. While the description of myinvention is in the singular as regards the turn-block, it is myintention to arrange one at each end skid of the log-support, so thatthe log is turned uniformly its entire length, or, if desired, more thantwo blocks may be provided, and, in fact, such will be the case in millsof unusual length, shaft K being, of course, of sufficient length tooperate the arms for all the blocks. Coiled spring R, arranged, asshown, on shaft K, counteracts the weight of the arms when turned downand renders the adjusting operation more easy.

Having thus fully described my invention,

what 1 claim, and desire to secure by Letters Patent, is-v p l. Thecombination of a skid formed with a transverse abutment, a log-turningblock movable vertically therein, an actuating mechanism and ashouldered link connecting the block and actuating mechanism ,theshoulder of the link engaging the skidabutment when the block is raised,thus locking lthe latter in elevated position, substantially as shownand described.

2. The combination of a skid formed with an abutment, an inclined tracktherein,a turn- After sawing one IOO block slidable on the track, anactuating mechanism, a link connecting the block and actuating mechanismand at its top formed with a shoulder, the link extending longitudinally of the skid and adapted to engage its shoulder with theskid-abutment after moving the block forward and upward on the track,substantially as shown and described.

3. The combination of the longitudinallyrecessed skid formed at its topwith a transverse abutment, the inclined track in the forward end of therecess, the block slidable on the track, a link hinged at its forwardend to the block and on its top formed with a shoulder adapted to engagethe abutment as described, an actuating-shaft, and a rock-arm on theshaft hinged to the rear end of the said link, substantially as shown.

In testimony whereof I aiiix my signature in presence of two Witnesses.

FRANZ S. THOMAS.
